Description

  The present invention relates to a track position data giving system and method for associating test value data output in time series from sensors installed in a vehicle traveling on a track with track position data.

  In a vehicle traveling on a track, in order to perform track maintenance, the state of the track is inspected, and as the inspection, for example, an inspection of the sway of the vehicle is performed using various sensors. .

  Conventionally, inspection vehicles such as track inspection vehicles are equipped with an encoder that measures the distance from the rotation of wheels to obtain track position data and an on-vehicle receiver that can receive track position data from the ground unit. The inspection value data and the orbital position data can be associated with each other.

  However, if it is attempted to acquire inspection value data with a normal business vehicle without using an inspection-dedicated vehicle, it is difficult to determine the track position because the device for acquiring the track position data is not equipped. There is a problem.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a schematic explanatory diagram showing an overall view of a track position data adding system in which a track position data adding method according to the present invention is implemented.

  In the figure, the orbital position data providing system 10 is roughly divided into a data recording device 12 that is installed on a vehicle and measures angular velocity, acceleration, etc., and records the angular velocity data, acceleration data, etc. acquired by the measurement, and on the ground. The data recording device 12 can be broadly divided into a data analysis device 14 and a charger 16 that analyze data recorded by the data recording device 12.

  The data recording device 12 includes a sensor unit 20, a recording circuit 22, and a battery 28, and is a portable device.

The sensor unit 20 includes an acceleration a _{x in} the traveling direction of the vehicle, an acceleration a _{y in} the horizontal direction of the vehicle, an acceleration a _{z in} the vertical direction of the vehicle, a roll angular velocity r _r that is a change in the roll angle of the vehicle, and a change in the pitch angle of the vehicle. A certain pitch angular velocity r _p and a yaw angular velocity r _y which is a change in the yaw angle of the vehicle are detected. For example, the sensor unit 20 is orthogonal to two micro inertial sensors (“MESAG” (registered trademark) manufactured by Tokyo Keiki Co., Ltd.) made up of an acceleration sensor and an angular velocity sensor that output triaxial acceleration and biaxial angular velocity. By arranging, these three accelerations and three angular velocities can be detected. Or the sensor part 20 can also be comprised from three separate acceleration sensors and three angular velocity sensors.

  As shown in FIG. 2, the recording circuit 22 includes a memory 32, a control unit 34 that stores inspection value data including angular velocity data and acceleration data in the memory 32, and an input unit 38. An A / D converter can be provided between the sensor unit 20 and the control unit 34 as necessary.

  The memory 32 can be an arbitrary recording medium that is integrated with or separate from the data recording device 12, and stores test value data including angular velocity data and acceleration data for each fixed period in time series.

  The input unit 38 is used to input commands for starting / ending measurement / recording.

  It should be noted that at least a part of the control unit 34 and the input unit 38 can be constituted by a portable computer such as a notebook personal computer provided with input means such as a keyboard and a mouse.

  In this example, the data recording device 12 serves both as a function for assigning orbital position data and a function for performing inspection necessary for track maintenance, and also serves as an inspection device. The inspection value data obtained from the sensor unit 20 is used for performing fluctuation measurement. When the data recording device 12 has only a function for giving the orbital position data, the sensor unit 20 may output only at least one-axis angular velocity data and at least one-axis acceleration data.

  The data analysis device 14 is constituted by a computer having a CPU, and the data analysis device 14 which is a computer is stopped as shown in FIG. 3 by executing a track position data addition program stored in the data analysis device 14. It functions as a position determination unit 140, a speed calculation unit 142, a travel distance calculation unit 144, a track position data association unit 146, and a repeated determination processing unit 150. The data analysis device 14 also functions as a data storage unit when the memory 32 is set or when data in the memory 32 is downloaded. The computer constituting the data analysis device 14 may be the same as the computer constituting a part of the data recording device 12, or may be different.

  The data analysis device 14 also includes a track position conversion table 42 in which the stop data on the track, the distance from the stop, and the kilometer as track position data are recorded, the inspection value data, and the track. A data output table 48 in which the kilometer as position data is associated is stored.

  As shown in FIG. 4, in the track position conversion table 42, the correspondence between the stop name, the travel distance from the stop, and the kilometer is recorded as one record. However, in this table, the correspondence between the travel distance from the stop and the kilometer can be omitted.

  The procedure of the orbital position data providing system and the orbital position data providing method configured as described above will be described.

1. Preparation Before Measurement The battery 28 of the data recording device 12 is charged by the charger 16 in advance, and a memory 32 having a recordable capacity is set in the data recording device 12.

2. Measurement on the vehicle In order to obtain the inspection value data including the angular velocity data, the data recording device 12 is carried to the vehicle, and the data recording device 12 is installed in an arbitrary place of the vehicle, for example, on a floor or a seat. At this time, the sensor unit 20 is installed so that the direction of the sensor unit 20 coincides with the coordinates of the vehicle.

  Prior to the measurement, arbitrary measurement reference data indicating the measurement start point or the kilometer of the measurement start point and / or the stop name, the track name, and the up / down are input from the input unit 38. However, since the information such as the kilometer of the measurement start point is known information before and after the measurement, it may be input in the data analysis device 14 in the ground processing described later.

  When the measurement / recording start command is input from the input unit 38, the data recording device 12 starts measurement and recording, and the data from the sensor unit 20 is time-sequentially regardless of whether the vehicle is stopped or running. When the measurement / recording end command is input from the input unit 38, the measurement and recording are terminated.

  After the measurement, the input unit 38 inputs arbitrary measurement reference data indicating the measurement end point, or about kilometer and / or stop name. However, also here, the information such as the kilometer of the measurement end point is known information before and after the measurement, and may be input in the data analysis device 14 in the ground processing described later.

  In this example, the inspection value data recorded in the memory 32 is traveling direction acceleration data, left / right direction acceleration data, vertical direction acceleration data, roll angular velocity data, pitch angular velocity data, and yaw angular velocity data, which are recorded in synchronization. Is done. The memory 32 records measurement reference data representing a measurement start point and a measurement end point. At this time, the acceleration data and the angular velocity data are associated with a common data ID (or serial number). Measurement reference data representing the measurement start point and the measurement end point is also associated with the data ID.

  When the vehicle stops at the stop during the measurement, the data from the sensor unit 20 is clearly different from that during traveling. In other words, while the vehicle is stopped, although there is fine vehicle vibration, the triaxial acceleration basically shows a constant value as shown below. Particularly, the acceleration in the traveling direction and the lateral direction are almost 0, and the acceleration in the vertical direction. Is almost 1G, and the angular velocity is almost constant and almost zero.

Acceleration in the direction of travel a _x ... almost 0
Left-right acceleration _ay ... almost 0
Vertical acceleration _az・ ・ ・ 1G
Roll angular velocity r _r ... almost 0
Pitch angular velocity r _p ... almost 0
Yaw angular velocity r _y ... almost 0

However, when the vehicle is tilted and stopped at the stop, the vertical acceleration may be slightly lower than 1G and the horizontal acceleration may be slightly higher than 0. As long as the acceleration is constant, the acceleration shows a substantially constant value corresponding to a known inclination.
Further, the amount of change of each acceleration and each angular velocity also shows a constant value of almost zero.

3. Processing on the ground After the measurement is completed, the processing shown in FIG. 5 is performed on the data recorded in the memory 32 by the track position data addition program by the data analysis device 14 on the ground, and the acceleration and angular velocity at the time of stopping are measured. The stop position is obtained using the tendency, and the inspection value data is associated with the track position data on the basis of the stop position.

First, a range of data in which the acceleration value output from the sensor 20 satisfies a predetermined condition is obtained (step S12). Here, the range of data to determine, it is possible to acceleration a _x in the direction of _travel, acceleration a _y in the horizontal _direction, from at least one of a certain value of the vertical acceleration a _z range is within a predetermined range. Specifically, the constant value is 0 in the case of the acceleration a _{x in the} traveling direction and 0 in the case of the acceleration a _y in the left and right direction, and 1 G in the case of the acceleration a _z in the up and down direction. If the vehicle is known to stop, the constant value may be one or more constant values depending on the slope at which the vehicle may stop.

Or, as the range of data for determining the acceleration a _x in the direction of _travel, acceleration a _y in the horizontal _direction, be in the range within a predetermined range from a certain value of at least one time change amount of the vertical acceleration a _z Can do. Specifically, the constant value is zero.

Next, a range of data in which the angular velocity value output from the sensor 20 satisfies a predetermined condition is obtained (step S14). Here, the range of data to determine, it is possible to roll angular velocity r _r, pitch angular velocity r _p, from at least one of a certain value of the yaw angular velocity r _y range is within a predetermined range. The specific value is specifically 0 in principle.

Or, as the range of data to determine, it may be a roll angular velocity r _r, pitch angular velocity r _p, a certain range from a constant value at least one is a time variation of the yaw angular velocity r _y within a predetermined range. Specifically, the constant value is zero.

  In step S12 and step S14, the predetermined range can be a value close to 0 including data noise and the like, and can be obtained in advance from data at the time of stopping by experiment.

  A data range in which the ranges obtained in step S12 and step S14 coincide is obtained (step S16). Data in this range is regarded as data when the vehicle is at the stop position and the vehicle is temporarily at the stop position. Here, the range of data to be obtained can be a range that continues in a predetermined time range corresponding to the stop time at the stop.

  Corresponding to the data ID between two adjacent stop positions that are considered to be at the stop position in step S16, the speed is obtained by performing time integration of acceleration in the traveling direction (step S18). Integration is performed to determine the travel distance from one stop position (step S19).

  Then, referring to the track position conversion table 42 from the obtained travel distance, the association between the data ID and the kilometer is performed from the correspondence between the distance from the corresponding one stop and the kilometer (step). S20). Alternatively, referring to the trajectory position conversion table 42 from the obtained travel distance, the data ID corresponding to the obtained travel distance is obtained by adding the obtained travel distance to the kilometer corresponding to one corresponding stop. It can also be the corresponding kilometer.

  When the vehicle stops halfway between the stops (in response to a stop signal or the like), the double time integration in step S19 is performed between two stops (that is, two adjacent stops regarded as stops in step S16). When the travel distance is obtained, it is conceivable that the error between the obtained travel distance and the distance between the two stops stored in advance in the track position conversion table 42 exceeds a predetermined range. If the error exceeds the predetermined range, the regarded stop is not a true stop, and the processing is performed sequentially with the data considered as the next stop. The error between the travel distance and the distance between the two stops previously stored in the track position conversion table 42 falls within a predetermined range.

  Even when the error is within a predetermined range, the travel distance between the two stops obtained by the double time integration is the distance between the two stops stored in the track position conversion table 42 in advance. The travel distance may be expanded and contracted to correct the travel distance, and the kilometer corresponding to the corrected travel distance corresponding to each data ID may be determined.

  The inspection value data, the determined speed, and the kilometer are associated with each other and stored in the data output table 48 (step S22).

  The correspondence between the inspection value data and the kilometer is repeated for the next stop, starting from the measurement or starting from the range of data considered as the first stop and the next stop. Go (Steps S18 to S24). Based on the table stored in the data output table 48, the analysis result is output as a form as required (step S26).

  In this way, by automatically determining the stop at the stop, there is no need to input a station stop signal during measurement on the vehicle, reducing the cause of human error, and measurement by workers Work can be reduced.

  By associating the travel distance between the two stops with the track position data, it is possible to reset the travel distance associated with the track position data at the stop, so that the calculated travel distance error accumulates. Can be prevented.

  By calculating the speed by time-integrating the acceleration in the traveling direction, the speed and the inspection value data can be associated with each other, and the correlation can be analyzed.

(Second Embodiment)
FIG. 6 is a functional block diagram of the data recording apparatus 12 according to the second embodiment. In the figure, members similar to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In this example, the data recording device 12 further includes a GPS device 26. The GPS device 26 includes a GPS antenna and a receiver, and outputs position data composed of latitude and longitude and speed data.

  In this embodiment, during measurement, the memory 32 stores data from the sensor unit 20 at a constant cycle and data from the GPS device 26 at another fixed cycle that is the same or different, in time series. Similarly to the data from 20, the position and speed data from the GPS device 26 are also associated with the data ID. In general, since the data acquisition cycle of the GPS device 26 is longer than the data acquisition cycle of the sensor 20, the position and velocity data are more intermittent than the acceleration and angular velocity data.

  FIG. 7 shows processing by the track position data adding program by the data analyzing apparatus 14 in this embodiment.

  In this embodiment, after performing the processing of steps S12 to S16, the latitude / longitude from the GPS device 26 is compared with the next latitude / longitude corresponding to the data ID between two adjacent stop positions, A change amount of latitude / longitude is obtained, converted into a distance from the change amount using a known conversion formula, and the distances are integrated to obtain a travel distance from one stop position (step S30). The following processing is the same as that of the first embodiment, and the same effect as that of the first embodiment is obtained.

  In this embodiment, since the latitude / longitude information is obtained from the GPS device 26, the measurement start position and the measurement end position may be specified without depending on the input, and the data determined to be at the stop position may be used. You may make it identify a stop from corresponding position data, and may make it discriminate | determine by this by the stop in the middle and the stop in a stop. For this purpose, the data analysis device 14 may prepare a table in which the stop and the position (latitude / longitude) information are associated with each other.

  When the data acquisition cycle of the GPS device is longer than the data acquisition cycle of the test value data, the acceleration in the traveling direction is applied to the data during the data acquisition cycle of the GPS device, as in the first embodiment. Interpolation may be performed by calculating the travel distance by performing double time integration.

  Further, by acquiring the speed data of the GPS device, the speed and the inspection value data can be associated with each other, and the correlation can be analyzed.

  Optionally, instead of performing the processing of steps S12 to S16, for data in which the speed value output from the GPS device 26 is within a predetermined range from a certain value, the vehicle is at the stop position, and temporarily It can also be regarded as data when is at the position of the stop. The specific value is specifically 0 in principle. The predetermined range can be a value close to 0 including data noise and the like, and can be obtained in advance from data at the time of stopping by experiment. Further, only data that continues in a predetermined time range corresponding to the stop time at the stop can be regarded as data at the stop position.

(Third embodiment)
FIG. 8 is a functional block diagram of the data recording apparatus 12 according to the third embodiment. In the figure, members similar to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In this example, in addition to the first embodiment, the recording circuit 22 of the data recording device 12 further includes a marking unit 36. The marking unit 36 can be operated manually, and when this operation is performed, the predetermined data is stored in the memory 32 in association with the data from the sensor unit 20.

  Further, the data analysis device 14 further includes a predetermined object table 46 (see FIG. 3). Information on predetermined objects other than the stop is recorded in the predetermined object table 46, and for example, association with bridges, railroad crossings, tunnels, kilometers of turnouts can be included. Further, the predetermined object table 46 can be integrated with the trajectory position conversion table 42 instead of being provided separately from the trajectory position conversion table 42.

  In this embodiment, an operator operates the marking unit 36 when stopping or passing the predetermined object during measurement. As a result, the predetermined data is recorded in the memory 32 in association with the data ID in synchronization with the inspection value data including the angular velocity data and the acceleration data obtained by the sensor unit 20.

  Moreover, in the process by the track position data addition program by the data analysis device 14 in this embodiment, the data ID that is regarded as data when the vehicle is at the stop position in step S16 and the data ID that is associated with the default data. The travel distance is obtained corresponding to the data ID between them (step S18).

  According to the third embodiment, in order to obtain the travel distance not only between two adjacent stops, but also between a stop with a shorter interval and a predetermined item, or between two adjacent predetermined items. Further, it is possible to further increase the accuracy of the correspondence between the travel distance and the kilometer.

  In the third embodiment, an operator's operation is required when passing through a predetermined object. However, since the input can be omitted at the stop, man-made work can be reduced.

(Fourth embodiment)
FIG. 9 is a functional block diagram of the data recording apparatus 12 according to the fourth embodiment. In the figure, the same members as those of the previous embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In this example, the data recording device 12 includes a GPS device 26 as compared to the third embodiment.

  In the processing by the track position data adding program by the data analysis device 14 in this embodiment, the ID data regarded as the data at the position of the stop by the step S16, the ID data associated with the default data, Corresponding to the data ID between them, the travel distance is obtained from the position data from the GPS device 26 (step S30).

  According to the fourth embodiment, as in the third embodiment, not only between two adjacent stops, but also between a shorter stop and a predetermined thing, or between two adjacent predetermined things. Thus, in order to obtain the travel distance, it is possible to further increase the accuracy of association between the travel distance and the kilometer. Further, although the operator's operation is required when the predetermined object passes, the input by the operator can be omitted at the stop, so that the work by the worker can be reduced.

  As described above, as described above, in addition to data indicating that the vehicle has passed a predetermined object such as a stop, a bridge, or a tunnel that is manually input directly from the marking unit 36, it is automatically passed by a separate sensor. It is also possible to use data representing the detection of. Or it can also be set as the data which detects automatically the passage of the ground element arranged at intervals along track, such as other ATS and data Depot (trademark) (made by Tokyo Keiki Rail Techno Co., Ltd.).

  In the fourth embodiment, it is possible to provide a correspondence table between predetermined latitude / longitude and kilometer, and manually check the position data from the GPS device 26 with the latitude / longitude of the correspondence table. The passage of the predetermined object may be determined without depending on it.

  In the above explanation example, the inspection value data is data commonly detected by sensors that detect angular velocity and acceleration.
